U can always ask Jogu the Drunk"Hey Jogu, what's the word on tomorrow's crops?" and if u plant what he says u get 7 crop instead of 5.

You actually get double crops if you plant what Jogu the drunk recommends (cost 10s to get him to tell you). Thats actually 10, not 7 :) You only get double crops on the plants he says, but you will occasionally get double harvest or extras on other crops too.
